This might seem like a question that has been answered before, but i tried looking and came up with nothing.

I am just wondering if anyone can give me the measurments for a test pipe for an eg hatch with a gsr motor. I want to have it made so i can put it on rather than drive up to a local shop with just my header and leave it with them

If you can give me this info that would be great oterwise dont post!

Measure your stock civic cat and add about 1.5" to that length That is roughly the gap that you are left with when comparing the GSR header to where the stock Civic cat should be (if you dont lenghten anything you have to pull your exhaust system forward that 1.5" and it hits stuff on the underside of the car and it's annoying). My friend had this problem with his GSR motor so I have personally seen the gap.

AMG

appreciate the post. Not sure though if i will take the chance, but then again I would hate to leave it at a broke down exhaust place with a newly installed gsr motor

AMG

anyone? I know there are at least 5-10 that have this in their hatch.......please lol

If you get a header for a 99-00 Si, there will be no gap to mess with.

Or he could take the advice I gave him and add 1.5" to the length he gets from measuring his stock civic cat. When I get to my computer later tonight I can show you pictures I took of a GSR header trying to mate up to a Civic Catalytic Converter/Exhaust system. I promise you the gap is just about 1.5"

Thanks for the advice, but i thought you were guessing

If you are certain that all i ahve to do is add 1.5 inches to my cat and tell them to make it that length and it will mate up without any further mod. Then i will do it.

Please let me know though if you have pics Thanks again

I have done many GSR/HB swaps and never had any issues with fittment, I have heard of it happening, but never actually experienced it...Hmmmm

Right because you probably had the correct test pipe so it eliminated the gap. Thats what i am trying to figure out so i dont have to drop it off at soem joe schmo muffler shop with my newly swaped motor

sammysnakes

it shouldn't take more than an hour for a muffler shop to make a test pipe. just wait at the shop while they make it.

AMG

Ok I am going next week to have it made..........I have been told earlier in the post that all i have to do is measue my cat and add 1.5 inches to it and the test pipe will fit?! Just seeing if anyone who has this swap can confirm before i go and have it made.
-Thanks

I agree. I'd just wait at the shop while they do it, or use the 1.5" method.
Don't leave your car there though.

i have a question. about that 1.5 inch gap. if you swap a jdm b18c1 or jdm b18c R motor motor into a 92-95 civic hatch dx, cx, or si, your saying that the stock manifold and down pipe will not bolt up to the stock cat and exhaust piping of the civic?? i thought that it would all bolt up just fine.. with no gaps

hatchboy93

does anyone on here know about this gap??? i talked about above in my previous post.

That`s been my experience....but as you can seee here, apparently that`s not always the case. Like I said, I`ve never had a problem, maybe this applies somehow to USDM motors and not JDM?
